Should I buy tickets before a Space Cowboys game?

I’ve been wanting to go to a game in Sugar Land since the Skeeters were playing there and this year I’m FINALLY going to make it. Should I buy tickets ahead of time or will there be decent seats left for a good price?

There's really no nosebleed section, right? So whatever's available will be good seats for a pretty good price, right?

I’m looking at going to the Saturday, May 11th game vs. OKC, if that makes any difference.
